The film is titled Nancy and is a “psychological drama” starring Andrea Riseborough, according to the entertainment website.

Here’s an excerpt:

Riseborough plays a serial imposter, who becomes perilously close to losing her entire identity — and the only person who’s ever truly loved her — when her elaborate lies inevitably unravel.

Principal photography has started in upstate New York with a crew comprised of all-female department heads. The film will be produced by Amy Lo, Michelle Cameron, and Riseborough. “Nancy” is a Mental Pictures, Mother Sucker, and Eon Productions movie, in association with Gamechanger Films.

Barbara Broccoli and Michael G. Wilson of Eon Productions will be among the executive producers, according to Variety.
